Application med .Tune 1,1.v 190s. saisine. 321.295.

vcitizen of the United States,A residing at Chicago, in the county of Coolr and State of Illinois, have invented'certain newand useful -Improvements in Metal litailufay-'liea of the metal incident sink unduly into l provided a tie for the metal parts to my improvements is to i I durable `tie of comparatively inexpensive construction 'winch 6, the edges of which which the following is a specication."

This inventionrelates to improvements in metal railway-ties and the especial object `of provide a strong and will possess the necessary supporting qualities with the desired degree of resiliency and one in which provision is made for the'expansionv and contraction of t temperature conditions. is to providea tie that will firm base, so that it will not the material with which the railroad-way is ballasted.

In carrying into effect my invention I have consisting chiefly of two pieces of sheet metal the tread or rail supporting member of which is tempered to give it the 'desired resiliency, and the other member is non-tempered and is 'preferably` heavier,

` A further object have a broad yand sans are provided for the expansive move-` mentsl of the tread member and other means for reinforcing said member at the points where it receives the greatest impact from i passing cars.

Ihave shown my invention in a; form in the which'- yFigure 1. is a perspective vie'w of a section of railway equipped withmy improved ties.

ig. 2 is a view in cross-section through one of my ties. Fig. 3 is a longitudinal section'- through one of my ties. Fig. 4 is a top plan view ofthe tread member of my tie.

Referring to the drawings in detail,- 5 represents a cement or concrete .base of suitable dimensions tovl'urnish anl effective support be described. This -base is preferably rounded along-its edges, as' shown, and, if desired, it may be reinforced by any of the well-known methods.

Arranged upon the base 5 is a metal plate are bont inwardly to forni thc overhanging .flanges 7. These flanges and the body portion of the plate belowthe flanges are perforated at intervals to receive bolts 8, b v which the plato is secured to thebase 5. .This plate preferably extends substantially the entire length of the base. Placed upon plate 6 is a plate 9,

preferred accompanying drawings, l 1n .rails 13 rest fre'e end/s upwardly and I baise-plate havmg The edgesy of the plate 9 are placed under the flanges 7 and have open, slots 19 cut there# in to receive loosely the 4.bolts 8, The trackv upon the center of the arched portion of the plate 9 and are removably attachedl thereto byohairs' 14, which Aare se-v cured to the plate by bolts and have their overlapping'the base or foot of the rails.- i i A tthe points where the-,rails rest upon the plate 9 the latter is reinforced by bent plates 11,'one end of .which is bolted to said plate, and the other 'end rests u on the plate 6. These plates 11 are made oiPspring-metal, 'so that they will yield 'and yat the same time be sufficiently stiff to afford vreinforcement toA 'the late 9 against lthe weight of trains. The thic pend upon the weight of the trains and rails which they are to support. l If desired, the reinforcing-plates may be inserted at points other -thaniilirectly under the rails and may be bolted to theplate' and have' their free end against the under side of the plate 9.

lt will be apparent, that as the plate 9 is flattened b v edges will have a sliding movement under the flanges, such-movement being limited by 1 the depth of slots 10,

'It will also be apparent that instead of securing theA member 7 to a concrete base it may be secured directly to the road-bed in any suitable manner, the essential elements of my invention being only the plates described.

` I claim as my invention`.

1. Rail-supporting means consisting of a base-platc having upturned and inturned edges forming channels, an arched treadthe flanges and the length of the plate arranged upon said base-plate, and

havin(r its edges slotted and looselv iittin0F Z5 b D ness of the plates A6, 9, and 11 will de-.

:2. Rail-supporting means consisting of a upturned and inturned edges forming longitudinal channels, an arched Vtreadeplate arranged upon said baseplate and having its edges fitting said channels, resilient means for reinforcing said tread-plates, and means for detach ably securing the tread-plate to the baseplate.
